Abstract

A pressurised filter, esp. for material delivered by a pump, has a massive cover (36) which supplies a release signal for operation of pump and filter only when in correct rotational position relative to the housing. The cover and the housing aperture include an emitter element, (optical, magnetic or inductive) and a sensor such as a Reed relay. A guide bolt travels in grooves with sections varying in slope, with one section having no slope but including recesses (62) in which the bolt can engage when the pump has been cut off, while the filter still contains pressurised material whose emission is undesirable.
